Evaluating Attacks on Function Grained K-ASLR in Encrypted Virtual Machines

Motivation and Task Description

Deployment of hardware-based security measures, such as AMD Secure Encrypted Virtualization (AMD-SEV), provide security for Virtual Machines (VMs) from a potential malicious hypervisor. Additional security functions, such as Kernel-ASLR and Function Granular KASLR, further help to prevent the hypervisor from gaining any information about the enrypted VM. This information is essential to execute successful attacks against those target VMs.

This thesis aims to evaluate which attacks against K-ASLR, employed in an encrypted VM, can be reproduced and how the employment of Function Granular K-ASLR influences the hypervisor’s ability to gather information from the VM.

Requirements

• Ability to work independently and accurately.

• Basic knowledge programming.

• Basic knowledge about the Linux Kernel.

• Basic knowledge about virtualization.
